"Today" is definitely localized in the Ajax Control Toolkit - it sounds like you are missing a satellite resource assembly.
If you have downloaded the binary distribution then in the folder where AjaxControlToolkit.dll
is found (release or debug, not sure which), you should also see a whole bunch of directories named according to culture code, such as fr, zh-CHT, ja, and so on, each one containing AjaxControlToolkit.resources.dll
.
You need to copy the language folders you want to your website's bin directory so that the resources will be loaded and used by the .NET runtime for the matching culture.
If you are just referencing AjaxControlToolkit.dll directly, you won't get the resource assemblies you need automatically, you have to manually include the ones you actually want.
